[01:43:31] <zeeshan> what kind of nonsense is visual basic
[01:43:35] <zeeshan> there is no binary handling in it
[01:43:36] <zeeshan> lol
[01:43:45] <alex4nder> you need to load some DLLs
[01:43:51] <alex4nder> it fixes everything
[01:43:58] <zeeshan> really?
[01:44:07] <alex4nder> on Windows, everything can be done with a DLL
[01:44:21] <malcom2073_> Yeah, just google the dll name, and download the first result that comes up
[01:44:22] <malcom2073_> totally legit
[01:44:47] <XXCoder> vasic basic lol
[01:44:51] <XXCoder> it sucks
[01:45:01] <XXCoder> my first langange was basic, then vb 3.0
[01:45:14] <malcom2073_> The good ol days of vb
[01:45:16] -!- furrywolf has quit [Ping timeout: 256 seconds]
[01:45:38] <XXCoder> malcom2073_: yeah then ms tried to make it serious language. lol
[01:45:51] <malcom2073_> Heh, should've left it in the realm of small task scripting languages
[01:46:04] <malcom2073_> VB6 was so horrid, and everyone tried to write everything in it
[01:46:05] <malcom2073_> it's like python
[01:46:29] <XXCoder> vb6 is bad
[01:46:47] <XXCoder> vb5 isnt too bad
[01:46:51] <malcom2073_> You want to talk about a bad language? I'm doing stuff in LUA right now.... oh man
[01:47:13] <XXCoder> in least its not cobol or brainfuck lol
[01:47:19] <XXCoder> tried coding in latter, too hard lol
[01:47:23] <malcom2073_> It's like it was written by 5 different people, who all had *different* opinions on how to do *everything*
[01:47:43] <malcom2073_> So there are of course, 10 different ways of doing every single thing, each one of them with their own quirks
[01:47:55] <XXCoder> just like c++ and java
[01:48:04] <malcom2073_> I'm not talking higher level concepts
[01:48:30] <XXCoder> okay an example? making sute I understood
[01:48:42] <malcom2073_> array assignment
[01:48:50] <XXCoder> that basic?
[01:48:52] <XXCoder> dang
[01:48:56] <malcom2073_> So, you can have an array, and set values like myarray[1] = 1, myarray[2] = 25
[01:49:10] <malcom2073_> but then if you do my array[25] = 30, and try to count the number of items in the array
[01:49:17] <malcom2073_> you'll get 25
[01:49:53] <XXCoder> so only 1,2,25 was assigned but number of entries is now 25?
[01:49:59] <malcom2073_> And you can't actually remove an item
[01:50:02] <malcom2073_> Right
[01:50:13] <malcom2073_> To remove an item you set it to "nil". But it's stil actually there, and in memory, just set to nil
[01:50:26] <XXCoder> what happens if int x = myarray[4]
[01:50:46] <malcom2073_> Error. BUT! If you do myarray[2] = nil, you can do int x = myarray[2], and it exists
[01:50:51] <malcom2073_> So you have two types of nonexistant values
[01:50:58] -!- bkboggy has quit [Quit: Leaving]
[01:51:05] <XXCoder> any way to probe and see if value exists?
[01:51:21] <malcom2073_> Yep, if (myarray[2] or nil == nil)
[01:51:27] <malcom2073_> that or makes it use nil, if it doesn't exist
[01:51:39] <XXCoder> interesting.
[01:52:11] <malcom2073_> So you can never actually remove items from an array, so be sure to reuse keys, because otherwise your indexes will get very large. But it's ok! Because they use doubles, so you'd never use them all!
[01:52:13] <XXCoder> " Multi-paradigm: scripting, imperative (procedural, prototype-based object-oriented), functional"
[01:52:13] <malcom2073_> *eyeroll*
[01:52:24] <XXCoder> lol
[01:52:47] <XXCoder> honestly I would add garbage collection for array
[01:52:58] <malcom2073_> I guess it's easier to use from the API side for integrating it into an application? It does make a pretty decent configuration scripting language, and the built in data serialization stuff is nifty
[01:53:00] <XXCoder> set to nil and it will move and reuse it for new array entry
[01:53:17] <malcom2073_> Oh! You want that? Guess what, 30 people have already written implementations for that, pick one.
[01:53:22] <XXCoder> fun
[01:53:22] <malcom2073_> You want classes? Another 30 options
[01:53:39] <malcom2073_> Ok I'm done ranting :P
[01:53:46] <XXCoder> lol yea
[01:53:55] <XXCoder> oh if you wanna good money, learn cobol
[01:54:01] <malcom2073_> haha I've heard
[01:54:04] <XXCoder> that stupid language will never die
[01:54:08] <malcom2073_> I'll stick to c++, I make good money with that for the time being
[01:54:18] <malcom2073_> And it's actually enjoyable
[01:54:20] <XXCoder> it will be around when captain kirk is around
[01:54:53] <XXCoder> and still around with time war future lol
[01:54:59] <malcom2073_> lol
[01:55:02] <XXCoder> seriously dunno
[01:56:02] <XXCoder> random tangent - I wish I could remember title but I really enjoyed this book on time travel - theres this group of humans from far future
[01:56:19] <malcom2073_> Heh
[01:56:30] <XXCoder> one day they found themselves in very advanced city, they know how to use everything, but they dont know anyone including themselves
[01:56:52] <XXCoder> so they worked together and try find what happened. just prior to that is time war and chaos so its hard
[01:57:04] <malcom2073_> Hmm
[01:57:25] <XXCoder> most of story is "present" but its interesting idea lol
[01:57:40] <malcom2073_> Wikipedia to the rescue maybe?
https://en.wikipedia.org/wiki/List_of_time_travel_science_fiction
[02:00:06] <XXCoder> dunno maybe will find it, still looking
[02:00:14] <XXCoder> you should read light of other days though
[02:00:22] <XXCoder> not the romoatic one but sci fi one
[02:00:27] <XXCoder> two books same name jeez
[02:03:14] <XXCoder> The Accidental Time Machine is pretty good but not best
[02:05:18] -!- per_sonne has quit [Ping timeout: 246 seconds]
[02:05:55] <XXCoder> ahh the time ships. very very very good book
[02:06:05] <XXCoder> malcom2073_: its direct sequel to the time machine
[02:06:13] <XXCoder> the orginial and probably first time travel book
[02:06:57] <XXCoder> timescape, good classic one
[02:07:25] <XXCoder> morlock night never knew there was old sequel to the time machine too
[02:08:26] <malcom2073_> hmm
[02:08:29] <XXCoder> ahh not really direct sequel, and unauthorized
[02:08:30] <malcom2073_> So many books haha
[02:08:33] <malcom2073_> I'll add them to my list though
[02:08:47] <XXCoder> the time ships is long read
[02:08:52] <XXCoder> but yeah good
[02:09:26] <XXCoder> I suggest read classic story before reading time ships
[02:09:29] <XXCoder> get the picture
[02:10:47] <XXCoder> heh I remember short story on time travel
[02:11:08] <XXCoder> it has one odd rule, people can travel to future 100 years a time jumps
[02:11:23] <XXCoder> but backwards? over 1.5 million year a jump
[02:12:03] <XXCoder> probably got backwards years wrong but its very long time
[02:12:25] <XXCoder> they found facts on what happened 100 years future, but guess how they got information 100 years before
[02:13:00] <malcom2073_> Heh
[02:13:14] <XXCoder> figured it yet? lol
[02:13:23] <malcom2073_> Archeologists?
[02:13:32] <XXCoder> nah event happened in future
[02:13:42] <XXCoder> they could easily go 100 years then figure stuff out
[02:13:45] <XXCoder> but bring info back...
[02:13:56] <malcom2073_> Have to go *really* far
[02:14:00] <malcom2073_> then jump back
[02:14:02] <XXCoder> yeah
[02:14:06] <XXCoder> that they did
[02:14:31] <XXCoder> they reported kinda happy news of future 1.5 million minus 100 years

[04:11:56] <jesseg> hey guys. Is there a cable available for servo motors - i.e. 2 or 3 thicker conductors inside a shield for the motor windings then a couple of small coax wires for the quadrature encoders?
[04:12:40] <cradek> they tend to be separate cables
[04:13:04] <jesseg> Ahh OK. What about a cable that's got two little coax's and a power lead for the encoder?
[04:13:23] <cradek> you don't use coax for encoders
[04:13:31] <cradek> encoders are generally differential, so you use twisted pairs
[04:13:49] <jesseg> well, what if you're on a budget and the encoders you have don't have differential outputs? :P
[04:14:16] <cradek> I've seen folks add differential drivers at the encoder
[04:14:16] <jesseg> "Get off the budget?" :D
[04:14:21] <jesseg> ahh OK
[04:14:25] <cradek> us digital even has little dongles that do that for you
[04:14:58] <RyanS> zee.... cutting tool, in the toolpost, so can't machine up to the dead center
[04:15:03] <cradek> you can try it without of course, and use a suitable time constant RC filter at the receiving end
[04:15:27] <cradek> it might work, especially if you keep the encoder lines away from the power lines
[04:16:20] <cradek> as your speeds get fast or your resolution gets high, an RC filter will round off and kill the signal, and you'll need differential
[04:16:21] <jesseg> I find small coax (i.e. 2.5mm, etc) to work pretty well for the encoder signals over some distance. Otherwise they pick up too much transients from the switching signal going to the motor or even from the other encoder channel
[04:16:23] <cradek> so ... it depends
[04:17:10] <ffurrywol> http://www.ebay.com/itm/Igus-Chainflex-VFD-Servo-cable-CF21-15-15-02-01-16-Gauge-power-signal-10-ft-/221263730386
[04:17:13] <cradek> I'm surprised ttl-output encoders will drive coax, but I don't know much about transmission like that
[04:17:37] <RyanS> It seems like the only fix is to make a longer tailstock leadscrew and ram
[04:17:59] <ffurrywol> the tailstock on my shoptask only has like 1" of travel.
[04:18:16] <cradek> ffurrywol: can't run much of a servo on 16 gauge wire can you?
[04:19:07] <jesseg> ffurrywol, wow cool! So they have thought of it. Not exactly the configuration I'm wanting but at least I know they thought of it!
[04:19:10] <RyanS> ffurrywol so how do yo machine with a dead center?
[04:19:13] ffurrywol is now known as furrywolf
[04:19:16] <cradek> http://www.usdigital.com/products/interfaces/encoder/cable-drivers/pc4
[04:19:26] <cradek> $15.70 qty 1
[04:19:57] <furrywolf> jesseg: I think all the control cable manufacturers have cables with bundled shielded encoder wires.
[04:20:06] <furrywolf> I just pasted that one because I got some a while ago. :)
[04:20:37] <jesseg> furrywolf, cooool. "Control cable" - maybe that's what I need to search for. I just don't knwo the right terms
[04:20:53] <RyanS> the ram and screw needs to be hardened, right?
[04:21:03] <furrywolf> you can also just look for "servo cable" :)
[04:21:07] <jesseg> I guess if I used differential drivers, then I could just use cat5e :P
[04:21:28] <furrywolf> RyanS: you need more than an inch for a center? it's only annoyed me when trying to drill, bore, etc.

[04:23:01] <furrywolf> jesseg: as a warning, if you buy retail, such cables are NOT CHEAP.
[04:23:24] <furrywolf> plan $5-$10+/ft
[04:23:28] <RyanS> furrywolf well , I want to machine the entire length of the part right up to the dead centre.... I can't get the tool to reach no matter which way I orient the compound & tool post
[04:23:51] <furrywolf> I got a MT3 extension sleeve for problems like that
[04:24:23] <furrywolf> you'd obviously want one for whatever taper you have. :)
[04:24:30] <RyanS> mt3->mt3 ?
[04:24:52] <furrywolf> yes
[04:25:17] <furrywolf> like
http://www.smithy.com/accessories/NDItMDEz
[04:25:22] <jesseg> furrywolf, yeah figures. I'll probably just use cheap thin coax for the encoders and see how that works. Same number of conductors, and no need to get line drivers.. however, I now wish that when I designed the servo board I'd used differential inputs :P
[04:25:37] <furrywolf> "Use this extension to give yourself some breathing room on the tailstock end of the lathe. If you are working with small lengths, you can use the extension socket to extend your tailstock set-up. This hardened steel socket with tang will add 3-1/2” to your set-up."
[04:26:23] <RyanS> hmm, I thought theres only mt4->3, 3->2.... This makes things easier
[04:27:06] <furrywolf> http://shopmasterusa.com/tools-complete-list/290-m3-m3-morse-taper-extension.html is the exact one I got.

[04:32:26] <RyanS> I love Australian prices,
http://www.machineryhouse.com.au/D402
[04:32:47] <RyanS> and sarcasm :)
[04:33:51] * furrywolf doesn't remember the AUD being 1/5th the USD...
[04:34:04] <alex4nder> RyanS: australia was a prison colony
[04:34:14] <alex4nder> so they price everything like you're buying cigarettes in jail
[04:34:15] <RyanS> Why would you want to extend the length if anything apart from a tail stock?
[04:34:34] <RyanS> ...right
[04:35:07] <RyanS> its not 1820 anymore
[04:35:16] <alex4nder> have you been to australia?
[04:35:23] <furrywolf> my mill only has 3" of Z travel, with shorter cutting tools not making it near the table. part of why I have one is for extending the tools so they reach the table. I haven't yet used it for this however.
[04:35:24] <alex4nder> the only thing cheap there is the cellphone plans
[04:35:36] <RyanS> I am Australian
[04:35:40] <alex4nder> RyanS: then you understand
[04:36:08] <alex4nder> last time I was in Perth, I paid 30 AUD for an old fashioned
[04:36:18] <RyanS> but it's not because we were a convict colony
[04:36:44] <furrywolf> don't you keep stealing our ozone? :)
[04:36:57] <RyanS> economy of scale
[04:39:18] <zeeshan|2> RyanS: i see what you mean
[04:39:30] <zeeshan|2> you're saying you can't sneak the tool near the live center
[04:39:47] <zeeshan|2> cause your carriage tool post hits the tail stock
[04:39:49] <RyanS> nope
[04:39:57] <zeeshan|2> try angling the compound
[04:40:05] <zeeshan|2> to 30 degrees
[04:40:09] <RyanS> i did
[04:40:10] <zeeshan|2> and rotate the tool post
[04:40:21] <RyanS> ditto
[04:40:25] <zeeshan|2> got a pic of your lathe?
[04:40:36] <furrywolf> or just order an appropriate extension. :)
[04:40:54] <zeeshan|2> furrywolf: i hate visual basic
[04:40:55] <zeeshan|2> :(
[04:41:09] <XXCoder> yay more dead bugs
[04:41:18] <XXCoder> really need to add screen to my window lol
[04:41:35] <furrywolf> everyone hates visual basic. why the hell would you ever touch it?
[04:41:52] <zeeshan|2> cause i dont know visual c#
[04:41:53] <zeeshan|2> :(
[04:41:55] <XXCoder> visual crapic
[04:42:01] <zeeshan|2> i wrote the program mostly in visual basic
[04:42:08] <zeeshan|2> im hoping to learn visual c# tonight
[04:42:13] <zeeshan|2> and transfer the code over
[04:42:19] <XXCoder> or just go java
[04:42:27] <XXCoder> javas decent for just quick coding
[04:42:28] <zeeshan|2> no libraries for java :/
[04:42:28] <furrywolf> I don't know C#. why not C++? :P
[04:42:30] <RyanS> laugh at price of my lathe
http://www.machineryhouse.com.au/L682D
[04:43:03] <zeeshan|2> RyanS: i have the same style lathe
[04:43:04] <zeeshan|2> 12x36
[04:43:09] <zeeshan|2> looks exactly the same lol
[04:43:28] <zeeshan|2> you gotta push the tool post out on the compound
[04:43:31] <zeeshan|2> and the compound at 30 degrees
[04:43:35] <XXCoder> heh I do want a lathe but from what I learned at work a bit, it's not fun
[04:43:40] <XXCoder> easy to do impact
[04:43:42] <zeeshan|2> and extend tailstock by 2.5"
[04:43:56] <zeeshan|2> XXCoder: im happy i have a lathe
[04:44:03] <zeeshan|2> in 2 weeks i migh t have a 600 part order!
[04:44:11] <XXCoder> whoo nice
[04:44:17] <zeeshan|2> im prototyping this weekend
[04:44:25] <zeeshan|2> 316L stainless :/
[04:44:49] <XXCoder> ow
[04:44:51] <RyanS> I'm guessing your using CNC for 600 parts?
[04:44:57] <zeeshan|2> yessir
[04:44:57] <XXCoder> I worked with stainless steel part at work
[04:44:59] <XXCoder> it was nasty
[04:45:08] <XXCoder> tools keep breaking down
[04:45:09] <zeeshan|2> i havent had issues with machining stainless on the lathe
[04:45:17] <zeeshan|2> but i had a hell of a time on the mill
[04:45:21] <XXCoder> lathe its apparently easier yes
[04:45:48] <RyanS> stainless , isn't that difficult but tool wears quick
[04:46:07] <XXCoder> yeah. I got too used to working with alum
[04:46:09] <zeeshan|2> http://turbozee84.altervista.org/machines/lathe.html
[04:46:15] <zeeshan|2> theres my lathe machining stainless
[04:46:15] <zeeshan|2> :D

[04:46:30] <zeeshan|2> sounds like butter
[04:46:54] <zeeshan|2> also ryan
[04:47:02] <XXCoder> arrgh shouldn't have fullscreened video
[04:47:04] <zeeshan|2> you can see in that video the tool will reach near tailstock no problem
[04:47:16] <XXCoder> awesome video, just can't stand handheld videos
[04:47:34] <XXCoder> my brain fucking sucks
[04:48:16] <furrywolf> bbl, wolfy bedtime

[04:48:52] <XXCoder> her friday may not be our friday
[04:48:56] <XXCoder> my friday was yeserday
[04:48:59] <furrywolf> I usually go to bed 9:30ish regardless of day of the week?
[04:49:04] <zeeshan|2> STAY UP
[04:49:11] <furrywolf> also, I'm in so much pain that being asleep would be nice.
[04:49:11] <zeeshan|2> its party time
[04:49:12] <zeeshan|2> i just got home
[04:49:15] * furrywolf doesn't party
[04:49:17] <XXCoder> I go to bed 2-4 am everday reardless of work lol
[04:49:23] <zeeshan|2> whats hurting
[04:49:25] <furrywolf> I get up at 5:30 for work
[04:49:38] <XXCoder> zeeshan|2: whats your age I forgot
[04:49:41] <furrywolf> back, neck, ribs, jaw, throat, ...
[04:49:44] <zeeshan|2> 30
[04:49:53] <XXCoder> ah still young enough and bit flexiable
[04:49:55] <zeeshan|2> the jaw and throat i can fix
[04:50:00] <zeeshan|2> ;)
[04:50:04] * zeeshan|2 hides

[04:55:05] <zeeshan|2> and really big things
[04:55:25] <XXCoder> yeah im sure you will always need hand drill
[04:55:25] <RyanS> like fabrication ?
[04:55:35] <XXCoder> drill press that is
[04:55:50] <XXCoder> RyanS: theres a hack that converts drill press into drum sander
[04:55:53] <XXCoder> easy to do
[04:55:54] <furrywolf> magdrill is good for really, really big things.
[04:56:06] <XXCoder> with wood platform and special drum that can be held by chuck
[04:56:19] <XXCoder> wood platform has vacuum attachment to keep dust down
[04:56:53] <XXCoder> from drill press to drum sander in literally minutes
[04:56:59] <XXCoder> then back in same
[04:57:18] <zeeshan|2> RyanS: to show i useful a drill press is
[04:57:19] <zeeshan|2> i have 2
[04:57:20] <zeeshan|2> lol
[04:57:27] <zeeshan|2> one always always always has a chamfer bit on it
[04:57:35] <XXCoder> RyanS:
https://www.youtube.com/watch?v=7WAU12uk6Ns
[04:57:52] <XXCoder> I need to get a good chamfer bit set
[04:58:33] <RyanS> zeeshan|2 did you keep the feed and headstock gearbox on your cnc lathe?
[04:58:42] <zeeshan|2> nope
[04:58:59] <XXCoder> sand the drumsander bit funny lol
[04:59:47] <RyanS> I would be reluctant to do that to my lathe, just because it actually cost a fair bit
[04:59:56] <zeeshan|2> RyanS: hehe
[05:00:04] <zeeshan|2> trust me, i was reluctant too!
[05:00:15] <zeeshan|2> you can always keep it
[05:00:18] <zeeshan|2> and remove the shear pin
[05:00:32] <RyanS> Can't you just disengage it?
[05:00:42] <zeeshan|2> itll be spinning for no reason then :P
[05:01:20] <RyanS> just take endgears off?
[05:01:27] <zeeshan|2> yes
[05:01:33] <zeeshan|2> but the internal gear box is still spinning
[05:01:34] <zeeshan|2> teh shaft
[05:01:51] <zeeshan|2> its not a big deal if it is
[05:02:49] <RyanS> hmm, I was thinking more how to re-purpose the glass scales in cnc setup. closed loop?
[05:03:27] <zeeshan|2> hook em up to a scope
[05:03:38] <zeeshan|2> and move em quickly and see if you lose the signal first :P

[07:24:58] <XXCoder> dunno one in video seems very nice
[07:25:18] <XXCoder> likely more money though
[07:25:25] <Jymmm> True, but when you get to the end of the video, you'll see how MASSIVE it really is.
[07:25:37] <XXCoder> yea
[07:25:46] <XXCoder> barely could watch the end so still frames

[07:27:02] <Jymmm> I do like that heavy duty trench though
[07:28:33] <Jymmm> I figure that if I use that downspout, the top/bottom pieces I'll cut out a slot on the 2" side to insert the pad, and
[07:29:28] <Jymmm> on the side pieces, have the 3" sides facing the pads and just cut 2x3" hole to fit the top and bottom pieces
[07:30:10] <Jymmm> I can add threaded rod for structural support if needed.
[07:31:21] <Jymmm> cheap, quick, and easy pad frame, waterproof, rustproof, and UV proof.
[07:31:57] <XXCoder> yeah right materials
[07:32:21] <Jymmm> And if there is too much calcium build up, instead of cleaning, just replace it.
[07:33:32] <XXCoder> isnt there couple chemicals usually used for fountains that stop calcium, algae and umm something else
[07:34:20] <Jymmm> You can use CLR or muratic acid to clean/loosen/remove calcium/lime build up, not that's about it
[07:34:34] <Jymmm> or white vinegar
[07:34:49] <XXCoder> ok

[15:30:41] <zeeshan|2> redlegion: lol
[15:30:49] <zeeshan|2> i use em for scribing!
[15:31:47] <redlegion> At least they have a use, I just tell my coworkers they aren't even allowed to put a "reference only" sticker on them.
[15:32:21] <zeeshan|2> they're actually suprisingly accurate
[15:32:40] <zeeshan|2> i havent noticed much difference between them and mitutoyo
[15:32:45] <redlegion> Depends on the lot, not all lots are created equal.
[15:32:48] <zeeshan|2> tried measuring gage blocks
[15:32:58] <redlegion> I've had to calibrate tons of harbor freight crap.
[15:33:21] <redlegion> They're about fifty fifty in whether or not they get thrown away
[15:33:26] <zeeshan|2> hehe
[15:33:30] <zeeshan|2> i get this brand:
[15:33:51] <zeeshan|2> http://www.canadiantire.ca/en/pdp/tools-hardware/measuring-tools/specialty-measuring/mastercraft-digital-caliper-0586800p.html#.VY7CXvlVhBc
[15:33:55] <zeeshan|2> it goes on sale for $15
[15:34:35] <redlegion> They look like rebranded centronic
[15:35:02] <zeeshan|2> even though i know they can measure as well as the mitutoyos
[15:35:11] <zeeshan|2> i use the mitutoyo when i really wanna be within a couple thou
[15:37:41] <redlegion> http://imgur.com/wx9wi6H
[15:37:51] <redlegion> That's pretty much all I need for what I do.

[15:43:22] <redlegion> How long have you been a machinist?
[15:44:31] <zeeshan|2> im not a machinist
[15:44:35] <zeeshan|2> i do it as a side business
[15:45:01] <redlegion> Ah.
[15:45:14] <zeeshan|2> im like batman
[15:45:21] <zeeshan|2> engineering in the morning
[15:45:28] <redlegion> I'm not a machinist, either. I did have a short stint as a button masher.
[15:45:35] <zeeshan|2> machinining/fabricatio/welding at night
[15:45:42] <redlegion> Nice.
[15:45:47] <zeeshan|2> then stripper overnight
[15:45:50] <zeeshan|2> (the last one is a joke)
[15:45:58] <redlegion> <.<
[15:46:12] <malcom2073> So you're a joke stripper?
[15:46:26] <zeeshan|2> unofrutnately most "machinists" are button mashers
[15:46:29] <redlegion> Like Chris Farley?
[15:46:31] <zeeshan|2> and quality control
[15:46:41] <zeeshan|2> in a production environment
[15:47:03] <zeeshan|2> deburr, cycle start, tool insert change after x parts, measure parts
[15:47:06] <malcom2073> zeeshan|2: Are you thinking machinest, or cnc operator?
[15:47:27] <zeeshan|2> cnc operator i guess :P
[15:47:34] <zeeshan|2> sometimes the jobs are advertised as "general machinist"
[15:47:47] <redlegion> That's terrible and ought to be forbidden.
[15:47:50] <malcom2073> Yeah you gotta watch for that heh
[15:48:07] <zeeshan|2> you can usually tell by the pay
[15:48:17] <zeeshan|2> $18-22 /hr for this type of job
[15:48:26] <zeeshan|2> a real machinist is around $30/hr
[15:48:35] <zeeshan|2> tool and die around $40/hr
[15:48:56] <redlegion> We have "engineers" that haven't obtained any degree and have never simulated stress or wear on any design or concept.
[15:49:03] <zeeshan|2> lol
[15:49:09] <redlegion> True story.
[15:49:13] <zeeshan|2> i test people that call themself an engineer
[15:49:19] <zeeshan|2> by 1 simple excerise
[15:49:31] <zeeshan|2> i give them a stress state and ask for the principal stresses
[15:49:35] <zeeshan|2> =D
[15:49:41] <redlegion> Nice.
[15:49:43] <malcom2073> I'm a software engineer :-P
[15:49:49] <zeeshan|2> (mech eng)
[15:49:54] <malcom2073> I know heh
[15:50:00] <zeeshan|2> malcom2073: have you programmed in visual c#
[15:50:02] <zeeshan|2> and basic?
[15:50:28] <malcom2073> zeeshan|2: I could be a dick and say "No such thing as visual c#", but yeah I've done most of the .net languages
[15:50:31] <malcom2073> :-P
[15:50:36] <zeeshan|2> okay c#
[15:50:37] <zeeshan|2> and c++
[15:50:39] <zeeshan|2> er
[15:50:40] <malcom2073> I try to avoid them unless the project calls for it
[15:50:42] <malcom2073> I mainly do c++
[15:50:42] <zeeshan|2> basic i mean
[15:50:52] <zeeshan|2> but c++ doesnt have automatic memory management
[15:51:11] <malcom2073> Neither does c#. It does have automated garbage collection though
[15:51:44] <zeeshan|2> im trying to decide which one to learn
[15:51:48] <malcom2073> For what?
[15:51:50] <zeeshan|2> or i should say F it
[15:51:53] <zeeshan|2> and stick to linux
[15:51:58] <zeeshan|2> and shit im familiar with
[15:52:06] <zeeshan|2> i wrote a small visual basic interface
[15:52:06] <malcom2073> c# works in linux to some degree
[15:52:18] <zeeshan|2> for my apparatus
[15:52:23] <malcom2073> What to learn, depends entirely on what you want to do.
[15:52:28] <redlegion> We hire "machinists" that know nothing about GD&T and can't trig a bolt pattern. :(
[15:52:29] <zeeshan|2> basically im controlling some gpio, reading some analog in
[15:52:32] <zeeshan|2> ouputting some analog out
[15:52:38] <zeeshan|2> redlegion: haha
[15:52:49] <malcom2073> Just to get started though, c# isn't terrible, and a lot of the syntax is the same with c/c++ so you can transition
[15:53:09] <malcom2073> .net is really got for simple GUI applications
[15:53:15] <malcom2073> for windows only
[15:53:16] <zeeshan|2> seems like c# doesnt have any typedefs
[15:54:31] <malcom2073> Yeah that's true
[15:54:47] <malcom2073> typedefs are *way* overused though
[15:54:55] <zeeshan|2> man i wish i could get the damn drivers working in linux
[15:55:05] <zeeshan|2> something has changed when they were written and modern linux
[15:55:22] <zeeshan|2> they were written for 2.6.x
[15:55:24] <malcom2073> Probably kernel versions heh
[15:55:32] <alex4nder> zeeshan|2: which drivers?
[15:55:32] <zeeshan|2> we're at like 3.xx
[15:55:40] <zeeshan|2> well they're not exactly drivers
[15:55:43] <malcom2073> yeah
[15:55:45] <zeeshan|2> they try to interface with libhid
[15:55:45] <malcom2073> What are they?
[15:55:58] <alex4nder> oh haha
[15:55:59] <zeeshan|2> they expect something to exist at /proc/bus/usb/
[15:56:05] <malcom2073> ahh
[15:56:06] <zeeshan|2> but that ppath doesnt exist anymore
[15:56:14] <zeeshan|2> its moved to /sys/bus/debug/usb now
[15:56:16] <malcom2073> Is there an equivalant that you can recompile them to use?
[15:56:24] <alex4nder> zeeshan|2: libhid has been dead as a doornail for a long time
[15:56:27] <zeeshan|2> well they compiled fine
[15:56:34] <zeeshan|2> but when i try to run the sample test program
[15:56:36] <zeeshan|2> it doesn't find the device
[15:56:42] <zeeshan|2> cause it's trying to look for crap using libhid
[15:57:13] <alex4nder> what application is it?

[15:58:04] <zeeshan|2> in that application
[15:58:42] <alex4nder> where is the code you're using that is linking against libhid
[15:58:52] <zeeshan|2> ftp://lx10.tx.ncsu.edu/pub/Linux/drivers/USB/
[15:58:56] <zeeshan|2> its in the tarball called

[15:59:46] <zeeshan|2> i found something else on their website im gonna give a try
[15:59:49] <zeeshan|2> http://www.mccdaq.com/solutions/DAQFlex-Solutions.aspx
[16:00:44] <alex4nder> 1.63 looks like it uses libusb?
[16:01:12] <zeeshan|2> is libusb
[16:01:17] <zeeshan|2> the modern usb management system?
[16:01:41] <alex4nder> libusb is just a library
[16:01:50] <alex4nder> but it's a supported library, that should be current and work with new kernels

[19:19:51] <zeeshan-lab> when you vpn into something
[19:20:02] <zeeshan-lab> do you get the network you're vpning into's ip address?
[19:20:19] <malcom2073> Depends on how the VPN is set up, typically though yes
[19:20:21] <zeeshan-lab> cause i notice i can ssh from another computer on the school network to it
[19:20:34] <zeeshan-lab> it being my destination computer that im trying to ssh into
[19:20:49] <zeeshan-lab> but when i try to do it from the home computer, no bueno
[19:21:05] <zeeshan-lab> so i installed the vpn application they specify
[19:21:16] <zeeshan-lab> and i connect successfully, but no ssh ability after still
[19:21:37] <malcom2073> Possible that their VPN software sticks you on a different network from student PC's

[19:36:16] <zeeshan-lab> thats the ipconfig stuff
[19:36:19] <zeeshan-lab> you can see the ip address there
[19:36:25] <zeeshan-lab> 130.113.90.97
[19:36:38] <zeeshan-lab> when i do ifconfig on the destination, it tells me this:
[19:36:47] <zeeshan-lab> 172.17.175.255
[19:36:56] <zeeshan-lab> but when i go on the internet and "what is my ip"
[19:37:27] <zeeshan-lab> i see this: 130.113.126.253
[19:37:55] <zeeshan-lab> not sure whats going on there :P

[19:38:59] <_methods> 130.113.90.97 is probably your tunnel ip address
[19:39:58] <zeeshan-lab> heres the other interesting thing, the other computer that is on the local network with ip addy 172.17.135.20 can access the destination comp no problem

[20:59:20] <ssi> anyone know if it's possible to flash a 7i90 which is connected via RS422 to a 7i77 which is connected to a 5i25? :P
[20:59:40] <norias> SolarNRG: can't... convert it?
[20:59:45] <norias> not a welder
[21:00:06] <norias> but i toss rusty stuff in a bucket of...
[21:00:10] <norias> phosophoric acid
[21:00:13] <norias> and water
[21:00:27] <norias> converts the rust to iron phosphate
[21:00:35] <norias> which is, it seems, a decent coating
[21:00:58] <SolarNRG> i got hydrochloric acid any use?
[21:01:13] <SolarNRG> whered u get phosphoric acid from?
[21:01:29] <norias> home depot
[21:03:58] <norias> look for rust remover
[21:04:01] <norias> or naval jelly
[21:04:13] <norias> there's at least one out there that's just phosophoric acid
[21:04:42] <malcom2073> evaporust is really good
[21:04:56] <pcw_home> ssi no, only interface that allows updating the FPGA code is EPP
[21:07:11] <pcw_home> well actually the hostmot2-ser interface should allow it but its untested and even if mesaflash
[21:07:12] <pcw_home> knows how to do this (And I don't know that it does) its probably only via a normal host serial port
[21:09:37] <ssi> gotcha... I think I can probably set up something to do EPP
[21:10:01] <pcw_home> if the sserial-remote config could do this, it would be nice, but I would have to add the support code
[21:10:02] <pcw_home> to emulate the method the DSPIC based remotes use to advertise and implement their flash programming
[21:10:07] <ssi> we talked a couple weeks ago about the possibility of doing commutation conversion in the 7i90
[21:10:16] <ssi> I'm trying to figure out the best way to get started on that

[21:11:04] -!- Deejay has quit [Quit: bye]
[21:11:05] <pcw_home> in some ways it might be nice to do it on a sserial remote config
[21:15:11] <ssi> the commutation conversion? or flashing
[21:16:10] <pcw_home> commutation (or you could just do it stand-alone)
[21:16:50] <ssi> I don't really know what you mean by a sserial remote config
[21:16:56] <ssi> this is what I'm trying to figure out:
[21:17:19] <ssi> each servo provides the regular quadrature encoder as well as the 4 bit greycode tracks
[21:17:32] <ssi> I need to count the encoders for normal linuxcnc motion
[21:17:45] <ssi> but I also want to use the encoder data for commutation
[21:18:15] <pcw_home> Maybe thats better done with a standalone config
[21:18:18] <ssi> will I be able to somehow write a firmware for the 7i90 that gets the encoder angle as a hm2 parameter, and wire it in via hal?
[21:18:47] <ssi> or should I have the 7i90 take the encoder signals in themselves and then repeat them out to wire to the 7i77?
[21:19:06] <pcw_home> standalone is probably easier
[21:19:20] <ssi> standalone meaning it doesn't interface with HM2 at all?
[21:19:26] <pcw_home> Yeah
[21:19:49] <ssi> so I'd need to wire the encoder to both places
[21:20:12] -!- zeeshan-lab has quit [Quit: KVIrc 4.2.0 Equilibrium http://www.kvirc.net/]
[21:20:17] <pcw_home> is this to convert Fanuc to something your drives understand?
[21:20:22] <ssi> to hall state
[21:20:42] <ssi> my OTHER option is to try to use 8i20s and the software bldc component
[21:20:45] <ssi> I bought one 8i20 to try
[21:21:19] <pcw_home> The software BLDC is pretty decent if you run a 4KHz or so servo thread
[21:21:54] <pcw_home> (just dont try on an Atom or other slow CPU)
[21:22:06] <ssi> D525 is what I'm using right now :/
[21:22:31] <pcw_home> good to 1.5 KHZ and that about it
[21:23:13] <ssi> I suppose I'll focus on the 7i90 option for right now then
[21:23:20] <pcw_home> the old Ebay Core Duos are _much_ better
[21:23:25] <ssi> I have a DC7800
[21:23:41] <pcw_home> yeah its say 3x as fast as a d525
[21:24:08] <ssi> ok so if I did a standalone converter with the 7i90
[21:24:35] <ssi> can I wire an encoder to both the 7i90 AND to the 7i77's encoder counters, or is that too much signal loading?
[21:25:47] <pcw_home> its ok though its single ended only
[21:25:57] <ssi> the 7i90 is SE only?
[21:26:10] <ssi> I thought it had LVDS
[21:26:31] <pcw_home> LVDS is no the same as RS-422
[21:26:40] <ssi> no I know
[21:26:48] <ssi> I thought there were differential IOs broken out on the 7i90
[21:27:20] <pcw_home> LVDS is possible bu RS-422 needs an interface
[21:28:07] <ssi> haha ok I'm lost
[21:31:36] <pcw_home> Hmm wish we had a 7I90 like card with Ethernet host interface and RS-422 I/O for this kind of translation task

[21:32:38] <pcw_home> I have a plan for it with the 7I94 but when I can get to it is another matter
[21:33:58] <ssi> oh here's what I was thinking of
[21:34:02] <ssi> from the webpage: "All I/O pins support 3.3V LVDS signaling."
[21:34:12] <ssi> I guess that doesn't necessarily mean that there are differential IOBs available
[21:35:22] <pcw_home> it does, all pin pairs are LVDS capable
[21:35:55] <ssi> ok, so can I use them to count differential encoders?
[21:36:13] <pcw_home> not really
[21:37:11] <pcw_home> if you biased them about 1/2 way up and divided the input signal by about 5, maybe
[21:37:14] -!- BellinganRoy has quit [Quit: Konversation terminated!]
[21:37:17] <ssi> is that because differential encoders are 5V and not LVDS's 3v3?
[21:37:49] <ssi> oh so differential encoders are actually using RS422 as the signaling standard?
[21:37:57] <ssi> sorry I'm a bit slow :P
[21:38:16] <pcw_home> because the chief benefit of differential is only gained if they still work with their -7 to +12 common mode range
[21:38:54] <ssi> so if I wire them single ended, the low line of each RS422 pair will be connected to a ground pin on the 7i90
[21:39:00] <ssi> and the high line will just be 5V ttl, is that right?

[21:40:33] <pcw_home> for single ended, you just use one signal of the pair

[21:48:44] <pcw_home> for LSTTL 3.3 probably lower than .8V for low and higher than 2V for high will work
[21:49:22] <ssi> ok let me get an encoder hooked up and see how it behaves
[21:50:35] <dolence> please, none using usb touch on latest release?

[22:05:02] <ssi> 3.4Vpp?
[22:05:21] <ssi> ch1 is A+, ch2 is A-
[22:05:27] <ssi> it's only wired to the 7i77, not yet to the 7i90

[22:08:20] <pcw_home> maybe... high is fine low may be noisy

[22:15:44] <ssi> the noise spikes in A+ I dunno where they're coming from, but the highest spikes are under about 1.4V on the lows

[22:19:38] <ssi> pcw_home: have a suggestion on which source I can start with for making a standalone firmware for the 7i90?

[22:23:53] <furrywolf> got my subaru aligned today... they didn't make the steering wheel point straight. I have to do that myself.

[22:24:19] <ssi> I opened up the seveni90.xise project and there's.... a lot... goingo
[22:24:21] -!- HardWall has quit [Ping timeout: 246 seconds]
[22:24:35] <ssi> going on
[22:25:27] <pcw_home> Not something I have done... for a full standalone config there's not much you can use except the ucf file :-(
[22:27:38] <pcw_home> I suppose if I did a standalone config that could use the hm2 I/O modules I would put in a little 32 bit CPU (B32)
[22:27:40] <pcw_home> and do all the piping in a little software loop

[22:30:11] <pcw_home> the hm2-ser config is like this (though it only has a 16 bit CPU)
[22:31:32] <pcw_home> so if you wanted to write your converter in assy language you could use the GPIO and encoder and whatever other hm2 modules were useful
[22:32:32] <pcw_home> you can read hm2-ser source code (assy lang) and see if it makes any sense

[22:42:46] <ssi> hm ok
[22:43:12] <ssi> otherwise I can just write a dirt simple bitfile that flashes one of the user leds just to confirm, right?
[22:43:27] <ssi> I had a converter started for my little cpld board, I can start with that code

[22:44:24] <ssi> trying to get to where I can flash this thing first of all
[22:44:37] <ssi> mesaflash wouldn't see it, but I just went into bios and the parport was in spp mode... changing to epp and I'll try again
[22:47:42] <ssi> yup that worked, flashed the ssremote firmware on there
[22:47:46] <ssi> now I can start trying to write something for it
[22:49:47] <pcw_home> just make sure you leave one EEPROM with EPP code in it
[22:50:26] <pcw_home> or you will be back to JTAG
[22:52:19] <ssi> oh hm so if I write a program that doesn't have the epp and flash it on the first eeprom, I'll lose my bootloader, yea?
[22:52:32] <pcw_home> yes
[22:52:44] <ssi> which means I won't be able to mesaflash a second time, correct?
[22:52:55] <ssi> unless I jumper for the other eeprom
[22:53:20] <ssi> I need to figure out what the procedure is to boot from the second eeprom but flash to the first
[22:53:54] <pcw_home> power cycle on second, move jumper write first
[22:54:00] <ssi> ok
[22:54:16] <ssi> that's easy enough :D
[22:54:31] <pcw_home> also easy enough to forget :-(
[22:56:19] <pcw_home> if you are messing with CPLDs you must have a JTAG cable
[22:56:27] <ssi> I did!
[22:56:30] <ssi> don't anymore :(
[22:56:34] <ssi> I need to order another one
[22:56:39] <pcw_home> :-(
[22:56:51] <ssi> I'm just now getting my EE lab set back up
[22:56:58] <ssi> half my crap is sooty and smells terrible
[22:57:08] <pcw_home> yuck
[22:57:19] <ssi> I'm getting black fingerprints all over my shiny new rigol scope
[22:57:43] <pcw_home> is the the $399 one?
[22:57:47] <ssi> yeah
[22:57:53] <ssi> it's SO WORTH $399
[22:58:04] <pcw_home> seems like a bargain
[22:58:10] <ssi> yeah very much so
[22:58:29] <ssi> especially considering you can unlock 100MHz bandwidth and the advanced triggers and serial decoding, and double the sample depth via a software key
[22:58:39] <pcw_home> maybe I should get one for home
[22:58:41] <CaptHindsight> nahh new tools were never cool, it's like 1st day if school with new crayons :)
[22:59:10] <ssi> it's a four channel scope and comes with four decent 150MHz probes
[23:04:01] <ssi> just hit pin 50 on the fpga with the scope
[23:04:10] <ssi> the hardware freq counter on the scope says it's 50.0001MHZ :D
